The purpose of this pilot study is to prospectively evaluate technical and non-technical skills, errors

and environmental factors in the hybrid angiosuite and correlate these with the postoperative

outcome and 30-day complication rate. An objective registration system, OR black box system will

be installed in the hybrid angiosuite, an environment where sick vascular patients are treated by

minimally invasive techniques using balloons, stents exposing both the patient and the team to

radiation. This system will evaluate what goes well, what does not go so well by recording

fluoroscopic images, the endovascular tools and machinery used, radiation dose, environmental

factors but also technical performance of the vascular surgeon and the team interactions with

various background (nurses, vascular surgery, anesthesiology).

The novelty of this pilot study is the prospective objective assessment of human and environmental

factors in the angiosuite as well as incidents, adverse events and patient outcomes to identify highrisk

interventions, to characterize a chain of events and to detect areas for improvement. Follow-up

projects will design training interventions both on an organizational level and on a team or

individual level to improve individual and team performance to prevent certain error patterns from

escalating into a near-miss, incident or adverse event and ultimately to deliver high quality patient

care in a safe working environment for the health care workers.
